Houston, TX; 23, October 2017: Most of the new car models from major automobile companies such as Ford, GM, Toyota, Honda, and Fiat come with complex lock and key systems called transponder keys. Transponder keys are a highly effective anti-car theft mechanism. The keys consist of an embedded chip which communicates with a small computer in the car. If the computer does not detect the signals from the transponder chip, the car does not start.
